摘要:: 芬顿反应通过产生强氧化性的活性物种去除废水中的难降解有机物，但是其严格的酸性反应条件及Fe³⁺向Fe²⁺的还原速率慢等问题限制了其规模化应用，引入络合剂可以有效解决上述问题。络合剂与金属离子络合可以减缓反应前期Fe²⁺的消耗速率，使得芬顿反应持续更长时间；同时，有助于提高金属离子在更高pH环境下的溶解度，将芬顿反应所需pH环境拓展至中性。此外，络合剂可以促进Fe³⁺向Fe²⁺的还原，改善芬顿反应中的限速步骤。需要注意的是，络合剂的种类、浓度都会影响有机物的最终去除效果。以芬顿反应的限制条件为出发点，介绍了络合剂强化芬顿反应的机理，将络合剂的种类、浓度对芬顿反应的影响进行了总结，并讨论了其现存的问题以及未来的研究方向。

Abstract:: Fenton reaction is capable of removing recalcitrant organic pollutants in wastewater through the generation of highly oxidative reactive species. However, its stringent acidic reaction conditions and the relatively slow reduction rate of Fe³⁺ to Fe²⁺ restrict its large-scale application. The introduction of chelating agents can effectively address the above-mentioned problems. Chelating agents complex with metal ions, which slows down the consumption rate of Fe²⁺ in the early stage of the reaction, enabling the Fenton reaction to continue for a longer period of time. Meanwhile, it helps to increase the solubility of metal ions in a higher pH environment, thereby extending the applicable pH range required for the Fenton reaction to near-neutral levels. Additionally, chelating agents can promote the reduction of Fe³⁺ to Fe²⁺, thus enhancing the rate-limiting step in the Fenton reaction. The type and concentration of the chelating agent can significantly influence the removal efficiency of recalcitrant organic pollutants. In consideration of the constraints of the Fenton reaction, this study elucidates the mechanism by which chelating agents enhance the Fenton reaction. Furthermore, it systematically summarizes the impacts of the chelating agents’ type and concentration on the Fenton reaction. Finally, the current challenges and potential future research directions are thoroughly analyzed.
